d4308a558d snapshot: fix max size limit check for COW device
Use proper max size as a multiple of extent size.
And use 64bit arithmentic for validation of minsize.
(in release fix).

362d8ead64 tests: more test run in cluster mode
aux updates:

prepare_vg now created clustered VG for cluster tests.

since dm-raid doesn't work in cluster, skip the cluster
test when someone checks for dm-raid target until fixed.

Reinstate the previous sort order for origin_size, so that LVs with

not the end.

fe22089edf thin: vgsplit support for thins
Support vgsplit for VGs with thin pools and thin volumes.
In case the thin data and thin metadata volumes are moved to a new VG,
move there also all related thin volumes and check that external origins
are also present in this new VG.

8bade9bfea cleanup: remove old and unused code to detect partition types
This part of the code has not been used for ages, if ever.

966d4f36d7 filter-mpath: detect partitions of mpath components
We use mpath filtering (enabled by devices/multipath_component_detection=1
lvm.conf setting) to avoid a situation in which we could end up with
duplicate PVs found. We need to filter out the mpath components and
use only the top-level multipath mapping instead for PV scans.

However, if the there are partitions on multipath components, we need
to filter out these partitions. This patch fixes it so those
partitions found on multipath components are filtered as well.

For example, let's consider following configuration:
The sda and sdb are mpath components, sda1 and sdb1 the partitions
on these components, mpath-test the mpath mapping and mpath-test1
the partition mapping - created automatically by kpartx right
after mpath-test creation. The PV resides on top.

       (LVM PV)
          |
      mpath-test1
          |
      mpath-test
          |
sda1 ---------- sdb1
   \ |        |/
    sda      sdb

E.g. for sda1 and sdb1, the code will detect this and it skips
the partition that belongs to the multipath component:
  <snippet from the log>
    #filters/filter-mpath.c:156         /dev/sda1: Device is a partition, using primary device /dev/sda for mpath component detection
    130 #ioctl/libdm-iface.c:1724         dm status   (253:2) OF[16384](*1)
    131 #filters/filter-mpath.c:196         /dev/sda1: Skipping mpath component device
  </snippet from the log>

Othewise, we'd see the same PV label on sda1/sdb1 and mpath-test1
at the same time ending up with "Duplicate PV found...".

65d0089c64 dev-type: dev_get_primary_dev fn: use dev_types and provide better return codes
The dev_get_primary_dev fn now returns:

  0 if the dev is already a primary dev
  1 if the dev is a partition, primary dev is returned in "result" (output arg)
  -1 on error

This way, we can better differentiate between the error state
and the state in which the dev supplied is not a partition
in the caller (this was same return value before).

Also, if we already have information about the device type,
we can check its major number against the list of known device
types (cmd->dev_types) directly, so we don't need to go through
the sysfs - we only check the major:minor pair which is a bit
more straightforward and faster. If the dev_types does not have
any info about this device type, the code just fallbacks to
the original sysfs interface to get the partition info.

c6f48b7c1a refactor: make device type recognition code common for general use
Changes:

- move device type registration out of "type filter" (filter.c)
to a separate and new dev-type.[ch] for common use throughout the code

- the structure for keeping the major numbers detected for available
device types and available partitioning available is stored in
"dev_types" structure now

- move common partitioning detection code to dev-type.[ch] as well
together with other device-related functions bound to dev_types
(see dev-type.h for the interface)

The dev-type interface contains all common functions used to detect
subsystems/device types, signature/superblock recognition code,
type-specific device properties and other common device properties
(bound to dev_types), including partitioning support.

- add dev_types instance to cmd context as cmd->dev_types for common use

- use cmd->dev_types throughout as a central point for providing
information about device types

bb70b38021 lvresize: improve poolmetadatasize
Fix the usecase when only PV list is specified.
With --poolmetadatasize PV list is used for metadata extents.
Without --poolmetadatasize PV list is used for 100% extension of LV.
Handle the case, when nothing could be resized (i.e. in dmeventd)

4937df4aed tests: extend harness
Add limit for buffer so if the test is running in some loop
and generating lots of output, the output log gets too large
for browser to display  (at least Firefox is quite confused
to display 300MB logs).

For now limit max output of one test to 32MB.
If there is need to see full log set LVM_TEST_UNLIMITED to
disable interruption of test.

harness now also prints max memory used during test,
it user and system time and amount of read/write operations.

c888c925b8 thin: enable resize for thin pool metadata LV
Support 'clasic' way of resizing of metadata LV.
Normally we disallow to work with internal 'invisible' devices.
But in this case we can make an exception and if user has some
special needs how to extend thin pool metadata LV - support it.

After resize of metadata LV, the pool will be suspended and resumed,
to be notified of this change.

87aca628d6 thin: lvresize supports pool metadata resize
Add support for lvresize of thin pool metadata device.

lvresize --poolmetadatasize +20   vgname/thinpool_lv

or

lvresize -L +20 vgname/thinpool_lv_tmeta

Where the second one allows all the args for resize (striping...)
and the first option resizes accoding to the last metadata lv segment.

f5a3bef276 format1: Fix snapshot reload in lv_remove.
The special suspend/resume code in lv_remove for LVM1 snapshots was interpsersed
with a vg_commit call. However, while with LVM1 metadata, vg_commit is
technically a no-op, the activation code relied on the ondisk and incore
metadata being the same, since on LVM1, a "commit" happens in vg_write
already. Since the "ondisk" metadata was previously not available with format1
(and incore was silently used instead, via lvmcache), the problem was masked.
